BALING-PRESS.

Specification of Letters Patent.

Patented Auo. 27, i918.

Application filed October 31, 1916. Serial No. 128,749.

To all whom it may concern Be it known that I, Jnssn J. STEWART, a citizen of the United States, residing at Yale, in the county of Johnson and State of Arkansas, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification.

An object of my present invention is to provide a new and improved baling press of a type that may be manually operated, and wherein the plunger is mounted in a manner whereby the greatest possible leverage may be obtained thereon during the baling operation so as to compensate, to some extent for the resistence offered by the material that is being baled, and to permit the same to be freely moved by the operator.

Another object of my invention is to provide improved means for actuating the plunger so that the same'may be made to exert a very great pressure upon the material that is being baled, even more so than the pressure applied to the operating` lever; and improved means to act in conjunction with the'said operating meansto assure the resetting of the plunger after the termination of the pressing stroke. Y

A further object of my invention is to provide improved means for retaining the plimger firmly in engagement with the material that is being baled, either during the baling operation, should the operator see lit to do so, or after the final pressing stroke thereof, so as to relieve lthe operatorrfrom duty at the operating lever in order that he may effect the tying of the bale or the removal of the same from the press.

A yet further object of my invention is to so mount the entire press that it may be easily and quickly moved from place to place, such as from one field to another when baling hay, alfalfa, or the like.

A still further object of my `invention is to so arrange the body of the press that the finished bale may be easily and quickly removed therefrom, and to provide suitable reinforcement therefor to compensate for the strain exerted during the baling operation. j

Another object is to provide an improved baling press of the type in question that is extremely simple in construction, strong and durable, and highly practical from both the standpoint of the manufacturer and the standpoint of the user; and which, it is believed, may be manufactured at a comparatively low cost.

Various other objects and advantages will b ecome apparent in the following description.

rlhese objects -a-re accomplished by means shown in their preferred form in the accompanying drawings, described in the follow ing specification and then more specifically pointed out in the appended claims.

In the accompanying drawings wherein like characters designate like parts throughouty the several views:

Figure 1 is a view in side elevation showing my invention as in its preferred embodiment. The body of the press, in this figure, is shownslightly broken away to disclose the plunger construction more clearly.

Fig. 2 is a view in cross section taken on line 2-2 of Fig. 1 looking in the direction indicated bythe arrows.

Fig. 3 is a view in perspective of a stub shaft that is mounted in the body of the press and illustrating to advantage the actuating pawl which is keyed thereto. a

In the drawings, numerals 10 and 11 designate skids upon which the other elements of the press are mounted. The skids are connected at certain points throughout their longitudinal extent by lateral joists 12, the latter being preferably formed of a strong and durable material inasmuch as they support, to a great extent the body portion of the device. In the formation of the floor structure of the press a plurality of planks or other supporting elements 18 are positioned on the joists 12, the same being approximately the same length as the skids 10 and'11 and may be formed of any suitable material, as wood or metal.

Sideboards 14 and 15 areV mounted intermediate the ends of the ioor structure, upon suitable standard 16, the upper ends of the sideboards being bridged by a cover 17. The cover 17 has an opening 18 formed at a. suitable point about which is mounted a hopper 19 to facilitate the placing of the material to be baled between the respective sideboards. In practical use it will be of coursenecessary to reinforce the sideboards and the coverto some extent in order that they may be made capable of withstanding the pressure exerted thereon during the baling operation. rhe type of reinforcing means used may be in the form of brace rods 2O such as shoivn in the drawing.

Posts 21 and 22 are positioned adjacent the ends of the floor struct-ure7 as shoivn in Fig. 1, Which are connected With the sideboards 1% and 15 by spaced beams 23 and 2st, vvhile cross heads 25 connect the upper ends of the posts 22- anth incidently, are connected .vith the cover 1T through the medium of the cover strips 2G. @n the other hand the upper ones of the beams 23 are connected, adjacent their outer ends. by a cross head 2?, the latter being reinforced through the medium of brace rods 2S. Suitable cover elements also connect the cover 1T and the cross head 2T.

Adjacent its one end, the tloor structure 13 hingedly supports a door 29, as at 30. which, when in a closed position is designed to close adjacent end of the press structure7 betvveen the posts 21, yet When in an open position will permit the ready removal of the bale. .lny suitable means may be employed to re iin the door 29 in aclosed position.

n plunger head 31 is mounted to operate between the sideboards l-land 15, it being of a size and shape to lit snugly f etiveen the said sideboards and between the floor strueture andthe cover 17. A plunger-beam 32 is carried by the said plunger head, through the medium of brackets 33, the said shaft being provided with a series of ratchet teeth Selthroughout a portion of its extent Whereby it may be actuated in the manner presently set forth, To more securely support the plunger-beam 32 and at the same time to provide for the free and easy movement thereof, certain of the beams 2d are provided with a cross arm 35, Whose stirrup portion 86 receives the shaft in the manner clearly shown in Fig. 2. rlhe provision of this cross arm also assures the retainment of the plunger-beam 32 in an approximately true horizontal plane at all times Which will of course materially add to the smoothness of operation of the plunger head 31.

1n order to retain the plunger head normally in a position to permit the insertion of material to be baled between the sideboards, through the hopper 19, 1 provide means in the form of a retractile spring 87, one end of which has connection with one of the posts at 3S, While its other end is connected as at 39 to one of the brackets 33.

A shaft .d0 is journaled through certain of the beams Qhin proximity to the plunger-beam 3 the same having an actuating paivl Ll1 fixed thereto for engagement With the teeth 3st of the plunger-beam. @ne of `the ends of this shaft e0 may be squared as at e2, to which is connected one end of an arm The other end of the arm et?) has connection with a member stel Which also connects with the operating lever y-155 the latter being pivotally mounted With respect- 'to the press structure as shown at 4G. Therefore, it ivill be seen that by drawing the operating' lever l5 toward the adjacent end of the press, the arm -l-B will be rocked in al manner to aetuate the shaft et() and cause the paivl l to engage with the teeth 3% of the plunger beam to move the plunger head 31 betvveen the side-boards. 1t ivill also be recognized that after releasing the operating lever -15 the spring 3T Will tend to draiv the plunger head to its normal position.

'linger l? is pivotally` mounted as at -1-8 and carries a stud a9 adjacent one end that normally bears against the arm a3, While an extension 50 thereof has connection With one end of a member 51 by which it may be actuated. The other end of the member 51 has connection with one arm 52 of a. bell crank lever or treadle that is pivotally mounted as at 53, the other arm of the said lever being' provided with a foot engaging portion 5l. Upon movement of the arm 113 during a pressing strekc of the plunger head 31 the finger .-ls' Will be rocked upon its pivot7 by reason of the engagement of the arm iv'th the stud 119j which movement will tend to raise the foot engaging portion 5a of the bell crank lever. Consequently at the termination of the pressing stroke of the plunger head 81 the operator may, by exerting a pressure on the foot enga-ging portion -l of the bell crank lever7 cause the arm 3 to be moved to its normal position which ivill carry With it the actuating paivl -Lll and thus permit the free actuation of the plunger head 31 and the plunger-beam 32 by the spring 3?.

To retain the plunger head 39 in pressing engagement With the material to be baled at any time the operator so desires` for instance at the time of the final stroke of the plunger head, 1 provide a slide catch that. may be moved into a position to engage certain of the ratchet. teeth 3st of the plungerbeam 32. This side catch may be mounted with respect to the press structure through the medium of brackets 56 such as will permit movement thereof when desired.

The material to be baled is deposited betiveen the sideboards 1l and 15 through the medium of the hopper 19 and Will be forced by action of the plunger head 31 toward the door 29. As more material is placed between the side-boards that `which has been lirst placed in the press Will be forced against the door 29 so that the completed bale will lie between the door 29 and the adjacent ends ot the sideboards 14- and 15.

After the completion of the bale, by tying the same in the usual manner the door 29 may be moved into an open position to permit the same to be easily and quickly removed from the press.

From the foregoing it is believed that the advantages and novel features of my invention will be readily understood and therefore further detailed description is deemed unnecessary.

In reducing my invention to practice I find that the form referred to herein as the most practical and preferred embodiment is the most eflicient, but realizing that certain conditions will necessarily vary in concurrence with the adoption of my device, I desire to emphasize the fact that various minor changes in the details of construction and in the proportions of parts may be resorted to when requred without sacrificing any of the advantages of my invention as defined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to Secure by Letters Patent is l. In a baling press, a structure to receive the material to be baled, a plunger mounted to operate in said structure, means to thrust said plunger in one direction, automatic means to return said plunger to its normal position, and atreadle to return said plunger-operating means to their normal position.

2. In a baling press of the character described, a structure to receive the material to be baled, a plunger mounted to operate in said structure, means including a hand lever to imparta thrusting movement to said plunger, a spring to return said plunger to its normal position, a treadle and means operable by said treadle to return said plunger-thrusting means to their normal position.

3. In a baling press the combination of a structure to receive the material to be baled, a plunger mounted to operate in said structure, a plunger-beam having teeth thereon and connected to Said plunger, means to support said plunger-beam intermediate of its ends, a hand lever, means operable by said hand lever to engage with the teeth of said plunger-beam and thereby impart a thrusting movement to said plunger, means to return said plunger to its normal position, a treadle to return said plungerthrusting means to the normal position thereof and means independent of said plungerthrusting means and mounted to be moved into a position to retain said plunger against return movement.

4:. In a baling press, the combination of a structure to receive the material to be baled, a plunger mounted to operate in said structure, a plunger-beam ltired adjacent one end to said plunger and having a plurality of teeth thereon, a pawl mounted to engage said teeth, an arm to move said pavvl and thereby impart a thrusting movement to said plunger, au operating lever arranged on said structure, means connecting said operating lever and said arm whereby said arm may be moved, means to return said plunger to its normal position, and means having engagement with said arm to return said pawl and said operating lever to their normal position.
